A very close friend of mine has been a Democrat all his life. Union family. Not a lot of discussion about politics in his household over the years because it was just a given that Democrats represented them best.
Recently he said he was in a checkout line somewhere and was behind someone who used an EBT card to buy hundreds of dollars of goods. He said it was the last straw for him because he realized he was working to pay for that person's spending as well as his own. He is now strongly supporting Romney & Ryan.
I know that's only one example but I speculate it is one of many more. The bad economy belongs to Obama. I am hopeful his moniker will change from The Won to The Wasn't (re-elected) next Tuesday.
I recall many adults when I was a kid who voted for Carter (grew up in heavily unionized blue-collar area). After that, they went Republican and never looked back.
I remember my own parents liking Carter because he was a Christian, just like them. To this day, among my entire family, Democrat = Evil.
I believe there will be another wave of such transitions. Some people are eternally stupid - the ones where obama could walk on stage smoking a bong and munching on a dead baby and they would still vote for him. But like in the days of Carter, I think a whole lot of people are suddenly having second thoughts about what they've always believed.
